This invention relates to concrete wall constructions and more particularly it is an object of theyinvention to provide a form for the casting of suoli walls.

. In the past, the most common way to cast concrete walls and the like has been to build forms of lumber, the latter being torn down after each wall is completed. Considerable waste and expense has been occasioned by this method since, although the lumber can then be reused, it is usually cut to certain sizes and must be re-cut for later work.

A further disadvantage has been in the length of time required to remove nails. Also, the labor cost of assembling such forms has been expensive because of the time required.

It is therefore an object of this invention to provide a form for constructing walls of concrete and the like which may be rapidly assembled.

Another object of the invention is to provide a form of this type, the various parts of which are prefabricated, so that no cutting is required.

Another object of the invention is to provide aconcrete form construction which is stronger and more rigid than heretofore.

A further object of the invention is to provide a concrete form the various parts of which are held together without the use of nails and in a manner whereby those parts of the forms which are disposed on opposite sides of a section of a nished wall are accurately spaced apart a selected uniform distance.

Still a further object of the invention is to provide a concrete wall construction which may be re-used without changing the dimensions of the several parts thereof.

Y .Yetanother object of the invention is to provide. a wall form construction the various parts offwhich may be economically manufactured l Other and still further objects and advantages of the-invention will become apparent-from the following detailed description of a preferred embodiment thereof.

lIn the drawings:

Figure 1 is a perspective view of a broken-away section of a concrete form of this invention showing its different parts;

Figure 2 is a side elevation of one of the bolts and spacer-sleeves employed, a portion of the spacer-sleeve being broken away; and Figure 3 is a top plan view of a broken-away end portion of one of the area-covering horizontally disposed wall form members employed.

f The form of this invention is for the construction of walls of concrete and the like and is best illustrated in Figure l in which may be seen a the other of said members.

plurality of types of upright standards each having a different construction, and each being employed in a different portion of the new form. A

f first group of the upright standards are two-wall corner sets and one of the latter is illustrated at IIJ.

Each of the sets IIJ include two, preferably equi-distantly spaced apart, elongated members I2 and I4. Each of the members I2 and I4 are provided with two longitudinal front surfaces I6 and I8, and 20 and 22. The surfaces I6 and I8 of the member I2 yare disposed at an inside right-angle with respect to each other; the surfaces 20 and 22 of the member I4 are disposed at an outside right angle with respect to each other.

Each of the surfaces 2B and 22 are disposed confronting and in parallelism with one of the surfaces of the other of the members I2 or I4. Thus, the surface I6 of the member I2 is disposed confronting the parallel with the surface 2o of the member I4; similarly the surface I8 of the member I2 is disposed confronting and in parallelism with the surface 22 of the member I4.

Each of the said surfaces are provided with flanges on their longitudinal terminal edges, each of the fianges being disposed at a right angle away from the parallel confronting surface of Thus, the anges 24 and 26 of the member I2 are disposed at a right angle away from the surfaces 23 and 22 respectively of the member I4; and the flanges 28 and 30 of the member I4 are disposed at a right-angle away from the surfaces I 5 and I8 respectively of the member I2.

The purpose of standards of the type I0 is to interconnect two walls where they intersect at a right-angle. Y

A second group of the standards are one-wall supporting sets, one of which is illustrated in Figure 1 and generally indicated at 40. The onewall supporting set 4! includes two, preferably equi-distantly spaced apart, elongated members 42 and 44. Each of the members 42 and 44 is provided with a longitudinal surface 46 and 48 respectively, the latter being disposed confronting and in parallelism with each other.

The surfaces 46 and 48 are each provided with and connected with two flanges 50 and 52, and 54 and 56, respectively. The flanges 50 and 52 of the member 42 are disposed at a right-angle away from the confronting surface 48 of the other member 44; similarly, the flanges 54 and 56 of the member 44 are disposed at a right-l 3 angle away from the confronting surface 5.5 of the other member 42. The flanges i! and 52 and 54 and 55 are all disposed in parallelism with each other, all longitudinal edges of the members 42 and 4d being vertically disposed in use.

The purpose of the one-wall supporting set 40 is for inter-connecting later described wall form members in a straight wall space.

A third group of upright standards are threewall corner sets for interconnecting later described wall-form members at the intersection etween an inner wall and an outer wall or at the point of junction of the terminal end of any wall with a continuous wall. For the purpose of designating this set a three-wall corner set, each wall section which terminates at the three-wall corner upright standard set will be referred to as a wall, even though two of such sections may be in alignment and be for the purpose of forming a continuous wall themselves.

One of the three-wall corner sets is generally indicated at 60, one of the three members of the G0 being designated by the numeral 52. The member 62 has two parallel, spaced apart flanges 54 and 66 interconnected by a center section 38 having a fiat surface disposed at a right-angle to and on the opposite side of the center section 68 from the flanges 54 and 56. The other two members of the three-wall corner set 60 are shown at 10 and 12, andO each is provided with a first flat surface 14 and 10 respectively, each disposed in parallelism with the flat center surface 58 of the member 52.

The members and 12 are further each provided with a second surface 18 and 80, each disposed at a right-angle to the surface 58, the surfaces 18 and S5 being disposed in confronting parallelism with each other, and preferably equidistantly spaced from each other. The surfaces 111, 16, 1S and 00 are each provided with a flange S2 on each of their longitudinal terminal edges.

The flanges 82 are each disposed at a right angle away from their adjoining surfaces and are disposed in directions away from those surfaces of the other members of the third set 0G, which surfaces are parallel with and confronting those surfaces connected to and adjoining each flange 82.

A fourth group of the upright standards are termed four-wall corner sets and are employed wherever four-wall sections meet in a building or other construction. One of such four-wall corner-sets is generally indicated at 90 in Figure l and includes four members 92, 94, 96 and 98, each of which is provided with two surfaces 00 and |62. The surfaces |00 and |512 of different ones of said members are disposed in parailelismwith and confronting each other.

Each of the surfaces |00 and |02 are pro-- vided with a flange ||0 on its longitudinal terminal edge. Each of the flanges IIB is disposed at a right-angle away from its adjoining surface |00 or |02 and away from that surface ilr or 02 of another of the four members 02, 05, and 98, which latter surface confronts the said adjoining surface to which the flange is attached.

A fifth group of the upright standards will be referred to as wall end standards and one of the latter is generally indicated at |20 in Figure 1. The wall end standards are preferably composed of only one member. as shown. That member |20 is provided with two longitudinal edges or 4 flanges I22 and |24 projecting outwardly therefrom in opposite directions. The flanges |22 and |24 are preferably disposed in alignment and are inter-connected by means of a U-shaped main body portion |26.

A plurality of normally horizontally disposed area covering, elongated wall form members |50 are provided. Each of the latter is provided with a substantially flat, preferably rectangular web or side surface |52, forming the center section of the member |50. Each member |50 is further provided with two parallel side flanges |54, each disposed at right angles with respect to its adjoining web |52. The flanges |54 are disposed on the longitudinal edges of the members |50.

The wall-form members |50 are each provided with U-shaped, preferably integral, ends |56 on the transverse edges thereof as best shown in Figure 3.

The ends |56 of each member |50 are provided with elongated recesses or slots |58 opening toward the surface |52 of that member. The slots E58 are disposed transversely of the members |50 and at right-angles to the flanges |54.

rl'he oppostely disposed walls |55 and |62 of each slot |58 are parallel and are spaced apart sufficiently for snugly receiving the projecting flanges of the various upright standards |0, 40, 65, or |20. All slots |58 and the flanges of said upright standards are preferably of uniform size.

The U-shaped ends |55, the flanges |54 and the surfaces |52 of each member |50 are preferably all formed by bending and cutting operations from one integral piece of metal.

The wall-form members |50 are each provided with two or more, and preferably four, like apertures |10 adjacent the ends thereof.

The members 50 are designed to be placed on either side of a pair of adjacent standards for cooperation with each other. Each aperture |10 of each wall-form member |50 is arranged for disposal in alignment with an aperture in the opposite wall-form member |50.

The aligned apertures |10 are for the purpose of receiving one of a plurality of bolts |12. As shown in Figure 2, the bolts |12 are provided with heads |14 and threadedly attached nuts |16.

Each of the nuts |16 are preferably welded to the adjacent wall-form member |50 around their corresponding apertures. This is for the reason that at times when the walls to be formed are below ground, or backed up against other walls, access to those nuts |15 which are on the outer side of the wall to be constructed are inaccessible to the operator during inserting and removing the bolts |12.

If desired, the walls of certain of the apertures |10 may be threaded and the nuts |16 eliminated.

Upon each boit |12 a spacing sleeve or annular spacing member |18 is attached, the latter being preferably of uniform length and of lengths corresponding to a desired concrete wall width. The sleeves |13 are of larger inner diameter than the diameter of said bolts and larger than the diameter of said apertures.

A plurality of like bolts |12 are disposed through the several upright members forming each one of the sets of standards. The bolts and apertures of the standards are spaced apart sufficiently for f purposes of strength. The standards are composed of two or more rigid upright members, the apertures in the several members of a standard, for receiving the bolts |12, are disposed in alignment with cach other similarly to the apertures in the wall form members |50.

n operation, the members forming the standards are bolted together, placed upright, and maintained in a desired position while the Wall form members |50 are placed in cooperating pairs on eitherl side of each two adjacent ones of the standards, the slots` |58 receiving the flanges of the standards and the surfaces |52 of the wallform members being disposed in confronting, spaced apart, parallelism. The bolts l'|2.with the spacers thereon are then inserted in aligned ones of theapertures and tightened so that the standards are held together and the wall form members are locked upon the standards holding themselves and the latter standards into a rigid structure. The spacers |18 for the standards and for the wall-form members are preferably of the same size.

The other wall-form members |50 may then be placed in tiers successively disposed one upon the other .until the spaces between the wall-form members and between the several parts of the upright members will form a continuous void or space in the shape of the walls of the building. The concrete, indicated at v20E) in Figure l, may then be poured into the said space or void and allowed to harden.

The bolts |12 may then be loosened and removed from the new concrete wall, permitting the removal of the wall-form members and the several sections or members of the standards I0, 40, 60, 90 and |00.

A concrete wall will be left standing, the sleeves |18 being left embedded therein. The standards and wall-form members may then be re-used again in a similar manner.

It will be seen that a wall thus formed may be easily strengthened by placing re-enforcing rods between the wall-form members and between the several members of each standard prior to the hardening of the cement, so that the re-enforcing rods will form a permanent part of the concrete.

The same sizes of standard members can be used for members 42, 44 and 62 and for members I4, lll, 72, 92, 94, 96 and 98, thus cutting initial costs of the forms. Similarly the wall-form members can be standardized into but a few lengths.

It will be further seen that a wall can be built in several portions by using the same set of wallform members, and even the same set of standards, for subsequent upper portions as for a rst horizontal portion of, for instance, the rst four feet.

Thus, to construct a twelve foot wall, for example, the latter would be built, using one-third the forms, by employing a single four foot high wall portion three times.

From the foregoing description, it is thought to be obvious that a form for concrete construction in accordance with my invention is particularly well-adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modication without departing from the principles and spirit thereof and for this reason, I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
